Steel fiber is a kind of fine steel wire with length and diameter in a certain range, which is added to enhance the performance of concrete.
Performance of steel fiber in concrete：
These disorderly distributed steel fibers can effectively prevent the expansion of micro cracks and the formation of macro cracks in concrete, significantly improve the tensile, bending, impact and fatigue resistance of concrete, and make the concrete have better ductility. At the same time, there are special anchor ends at both ends of the steel fiber, which can enhance the grip with the concrete. When the concrete is deformed, the anchor end can effectively transmit and distribute the stress, so that the cracks can be resolved into micro scattered micro cracks.
Scope of application：
Ground, road, railway, tunnel, water conservancy, power station, subway, segment, airport, dam, bridge, wharf, mine, metallurgy, mineral, environmental protection, industrial plant and civil construction.
